NIPPLE-CHUCK.

SLDECIFIGATION forming part of Letters Patent No. 741,954, dated October 20, 1903- Application filed April 4, 1903. Serial No. 151,159. (No model.)

.T0 @ZZ whom/ t motyconcern:

Be it known that I, BRADFORD BoRDEN, of Warren, in the county of Trumbull and State of Ohio, have invented certain new and useful Improvements in Nipple-Chucks; and I do hereby declare the following to be a full, clear, and `exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of this invention is to providea chuck for pipe-nipples composed of but few parts and which shall be strong and durable, insuring the holding ofthe pipe-nipple tightly and squarely in place.

A further object is to eect the holding of the pipe-nipple wit-hin the chuck without the use of screw-threads, thereby rendering the operation of the device quick and certain and avoidingr the dangerconsequent upon the wear of threads.

The invention will be hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a longitudinal sectional View. elevation with the nipple-bushing removed and shown slightly turnedaxially relatively to the'rest of the chuck. Fig. 3 is alongitudinal section with parts broken away. Fig. 4 is similar to Fig. 3 with the nipple-bushing locked in place. Figs. 5 and 6 are details.

Referring to the drawings, 1 designates the tubular casing having a central bore 2 and a circular opening 3 in its closed end 4, such end being slightly reduced on its exterior to receive the inner end of the nipple-bushing 5, having arms 6, extended into keyways 7, formed in opposite sides of the casing. These arms on theirV inner faces have lugs S, which are seated within slots 9, formed in opposite sides of a retaining-washer l0, such washer being held within the casing by'a screw 12.

13 is a rod or bar extended longitudinally through the casing, being guided by a fixed disk 14, held by a screw 15. A pin 16, extending laterally from this rod through a slot 17 in the casing, forms a handle by which the rod may be turned axially to effect the locking and unlocking of the nipple bushing. The other end of rod 13 is square in crosssection, and hence passes loosely through the Fig. 2 is a side opening in washer 10 andalso through the opening 8. Between this washer and a shoulder formed by the closed end 4 is a lockingwasher 18, having a central square opening eonformingto the square portion of the rod, so asto turn with the latter and yet allow the rod to move longitudinally. In the periphery of this washer 18 `are opposite slots 19, which when coincident with the slots 9 and similar slots 2O in opposite sides of the casing form subkeyways or continuous grooves which allow the bushing to be inserted into or removed from position. When this bushing is positioned with its lugs seated in slots 9, the axial turning of the rod 13 will cause washer 18 to lock such lugs within said slots, and thereby securely hold the bushing in place, all lateral movement being prevented by the arms within the keyways.

21 is a nipple-engaging stop-disk, located within the nipple-bushing and iiat on its outer face, while from its inner face projects a concaved boss 22, designed to receive and accommodate the end of the actuating-rod 13.

23 is an adjustingwedge, passed transversely through the casing through opposite openings 24, such wedge being designed when forced inwardly to engage the handled end of rod 13and thereby move such rod longitudinally and force it and the disk 21 forward hard against the end of the nipple screwed into the bushing,thereby tightly and securely holding the same in place. The chuck-casing, with its attached nipple, may then be placed in a pipe-machine and held like an ordinary pipe during the threading of the nipple.

As is well known in the art, nipple-bushings of various sizes are required in conjunction with nipple-chucks.V By means of my invention the nipple-bushing may be readily removed andV another substituted, the release and securing ofthe bushings being easily effected by an axial turning of the holding-rod. The rm tightening and holding of the nipple is readily and easily accomplished by driving the wedge transversely through the casing, such wedge forcing the rod and nippleengaging stop-disk tight against the nipple.

A chuck thus constructed embodies many advantages in point of simplicity, durabil- ICO ity, inexpensiveness, and certainty of operation.

I claim as my invention 1. A nipple-chuck havinga longitudinally and axially movable rod, a nipple-bushing,

vmeans actuated by the axial turning of the rod for locking said nipple-bushing,and a disk for engaging the nipple when the rod is moved longitudinally, as set forth.

2. A nipple-chuck comprising a casing, a detachable nipple-bushing, a nipple-engaging stop-disk, a rod movable longitudinally within the casing engaging said stop-disk, and means actuated by the axial turning of the rod for locking such bushing to the casing, as set forth.

3. A nipple-chuck comprising a casing, a detachable nipple-bushing, a rod extended longitudinally through the casing, means actuated by such rod for engaging and locking such bushing, a nipple-engaging stop-disk, and means for forcingsaid rod longitudinally and holding said stop-disk against the nipple, as set forth.

4. Anipple-chuckcomprising a casing having keyways, a detachable nipple-bushing having arms fitted'in said keyways and lugs extending from said arms, a nipple-engaging stop-disk, an axially-movable rod engaging said stop-disk, a locking-washer movable axially with said rod for engaging said lugs, and y means for forcing the rod longitudinally against the stop-disk, as set forth.

5. In a nipple-chuck, a longitudinally and axially movable rod having a squared portion,

'a lockingwasher having slots and a square 6. The combination with the tubular casing having keyways at one end and opposite openings at or near the other, of the nipplebushing having arms/fitted in said keyways, lugs on said arms, seats therefor, a rod extended longitudinally of the casing having a squared portion, a locking-washer fitted on' said squared portion and vhaving slots designedlto coincide With said seats, a nippleengaging disk, and a Wedge passed through said openings for forcing said rod against said disk, as set forth.

7. The combination with the tubular casing having a slot and opposite openings, of a detachable nipple-bushing having opposite lugs, a nipple-engaging disk Within such bushing, a rod movable axially and longitudinally Within the casing and having a squared portion, a locking-washer for engaging said lugs having a squared opening to accommodate said rod, a pin extending from the latter through said slot, and a Wed ge passed through said openings of the casing for engaging said rod, substantially as set forth.

8. The combination with the casing having at one end keyways formed with central grooves, of a nipple-bushing having arms f1tted in said keyways, lugs projecting from said arms fitting in said grooves, a locking-Washer having opposite slots for coinciding with said grooves, a rod for turning said washer to lock said lugs in said grooves, a nipple-engaging stop-disk, and means for moving the rod longitudinally independently of said locking- Washer, as set forth.

1n testimony whereof I have signed this specification in the presence of two subscribing Witnesses.
